This has been driving me insane for about an hour now, so I am hoping someone else has used the site before, and can give me the name/link. I am fairly sure the "game" starts with M, but not certain. Anyway, you have a square, and you click inside the square to set a ball in motion. When the ball impacts a wall, it makes a tone. You can put out multiple balls, and if they bounce into each other, they reflect backwards, which allows you to make interesting patterns of music. This isnt the ball thing where you draw your own walls, and balls drop. The game I am talking about they just go vertical or horizontal only. No diagonals (that I remember) or anything like that.

PLEASE someone know what the place is... Been trying everything I can think of on Google, and I am coming up empty handed...

Yeah, but it isnt the same. There is a specific sound that I am after from this particular thing. Tone Matrix is almost what I am after, but not quite. It has the right tones, but not the same ability to make random patterns.
